Ingredients

  • 3/4 pound boned beef top sirloin, about 1 inch thick
  • 1/4 pound thin-sliced mushrooms
  • 1 onion (1/2 lb.), thinly sliced
  • 2 tablespoons Hungarian or domestic paprika
  • 8 ounces dried egg noodles
  • 1 cup beef broth
  • 1 tablespoon cornstarch
  • 1 cup nonfat or low-fat sour cream
  • 2 tablespoons chopped parsley
  • Salt and pepper

Method

  • Trim and discard fat from beef. Cut the meat across the grain into 1/8-inch-thick slices.
  • Place a 12- to 13-inch nonstick frying pan over high heat. When pan is hot, add beef and stir-fry until meat is lightly browned, 2 to 3 minutes. Pour into a bowl.
  • Add mushrooms to pan and stir often until browned, 3 to 4 minutes. Add to beef.
  • Add onion to pan and stir until lightly browned, about 2 minutes. Reduce heat to medium and stir paprika into onion.
  • Meanwhile, cook noodles in about 3 quarts boiling water until barely tender to bite, 4 to 5 minutes. Drain and place on a large platter; keep warm.
  • Mix broth and cornstarch; add to onion mixture and stir just until mixture boils, about 2 minutes.
  • Return beef and mushrooms to pan and stir until hot, about 1 1/2 minutes. Add sour cream and stir just until hot, about 1 minute.
  • Spoon meat mixture over hot noodles. Sprinkle with chopped parsley and season to taste with salt and pepper.
